For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet that sits some 3,000 miles (4,828 kilometers) below the surface.

Well, the verdict is in. The Moon is not made of green cheese after all. A thorough investigation published in May 2023 found ...

For decades, noble gases like helium have been considered chemically inert, refusing to form stable bonds under normal conditions. But new research challenges this assumption, revealing that helium ...

Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating more material in some areas and less in others — almost like creating hills ...

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have ...

Why Trust Us? A new study analyzing decades of seismogram data shows that physical changes can occur at the surface of the Earth’s inner core. This means that the surface of the inner core could ...

Scientists confirm the Moon has a solid iron core, like Earth’s, with a molten outer layer. This discovery reshapes our ...

Scientists have confirmed that the Moon has a solid inner core with a density similar to iron. The core's structure mirrors that of Earth's, with a fluid outer layer and solid inner core ...

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the ...

They found that the inner core once spun faster than Earth itself ... Shape changes in the core could hold clues about the forces deep inside Earth that power our magnetosphere, the invisible ...

A recent study revealed that Earth’s inner core is slowing down, prompting scientists to investigate further. Their research led to an unexpected discovery: that inner core is not entirely solid.

They found that the inner core once spun faster than Earth itself ... Shape changes in the core could hold clues about the forces deep inside Earth that power our magnetosphere, the invisible ...
